I still remember sitting in the clinic chair for my very first lip flip, wondering if it would really make that subtle, “just right” enhancement I’d been seeing all over Instagram. The injector assured me it would be quick, almost painless, and the perfect way to make my upper lip look fuller without the commitment of fillers. But what I was really curious about was this — how long does a lip flip last?

If you’re wondering the same thing, you’re not alone. Duration is one of the most common questions people ask before booking this trending cosmetic treatment. In this guide, we’ll explore exactly how long you can expect results to last, what affects the timeline, and how to make your lip flip look fabulous for as long as possible.

What Is a Lip Flip?

Lip Flip Before And After

A lip flip is a non-surgical cosmetic procedure that uses very small doses of botulinum toxin — most often Botox — to subtly enhance the appearance of the upper lip. By relaxing specific muscles around your mouth, the upper lip “flips” upward slightly, exposing more of the natural pink tissue.
Unlike fillers, a lip flip doesn’t add physical volume. Instead, it enhances what you already have, giving a softer, more relaxed smile. It’s especially popular with people who want a small change, dislike a gummy smile, or want to test the waters before trying fillers.

How Does a Lip Flip Work?

The treatment targets the orbicularis oris muscle — the circular muscle around the mouth. Small injections are placed at the cupid’s bow and near the corners of the mouth.
As the muscle relaxes, the upper lip gently rolls outward. This creates the illusion of more fullness and definition, without the use of filler products.
Most appointments take less than 15 minutes, involve minimal discomfort, and require no anesthesia, though a numbing cream can be used for sensitive patients.

Lip Flip vs. Lip Filler — Which Lasts Longer?

Lip Filler

Although both are popular lip-enhancement treatments, they differ in technique, results, and longevity. Here’s a side-by-side comparison:

Feature Lip Flip Lip Filler
Method Botulinum toxin relaxes muscles Hyaluronic acid gel adds volume
Longevity 2–5 months 6–12 months
Look Subtle, natural Fuller, plumper
Cost $80–$200 $500–$1,000+
Downtime Minimal Possible swelling/bruising for a few days
Best For Subtle enhancement, gummy smile correction Significant volume increase

If you’re looking for a low-cost, low-commitment option, a lip flip is ideal. For those wanting dramatic, long-lasting results, fillers are the way to go.

So, How Long Does a Lip Flip Last?

On average, a lip flip lasts between two and five months. This range depends heavily on your body’s metabolism, the amount of product used, and how well you care for your lips afterward.
If you want a consistent look, you may need maintenance appointments every two to three months. Over time, some patients find their results last longer as the treated muscles adapt to repeated relaxation.

Factors That Affect How Long a Lip Flip Lasts

Factors That Affect How Long A Lip Flip Lasts

Several elements determine whether you’ll enjoy your results for two months or closer to five:

Metabolism Speed

People with a faster metabolism break down botulinum toxin more quickly, meaning results fade sooner.

Lifestyle Choices

High-intensity workouts, smoking, frequent sun exposure, and stress can all shorten the life of your treatment.

Dosage and Technique

The number of units used and the injector’s skill level make a difference. Too little product may fade quickly; poor placement can lead to uneven results.

Skin and Health Condition

Good hydration, healthy nutrition, and strong skin integrity can help prolong the effects.

Treatment History

First-time patients may notice shorter results compared to those who have had multiple lip flips, as the muscles adapt to staying relaxed.

When Will You See Results After a Lip Flip?

Results are not instant. You’ll usually see changes within three to five days, but it can take up to two weeks for full effects to develop.
During this period, the muscles gradually relax, allowing your lip to roll outward naturally. For many people, the final look is more noticeable in photos than in the mirror — it’s subtle, but it makes a big impact.

What to Expect During the Procedure

A lip flip appointment is quick and straightforward. After a brief consultation to discuss your goals, the injector will clean the area and place a few small injections. Most patients describe it as a light pinch.
The entire process usually takes less than 10 minutes. You’ll be able to resume normal activities immediately, though some mild swelling or redness is possible.

Recovery & Aftercare for Longer-Lasting Results

The recovery process is simple, but your aftercare habits can influence how long your results last. For the first 24 hours, avoid touching, rubbing, or pressing your lips. Stay upright for at least four hours post-treatment and skip intense exercise until the next day.
In the weeks that follow, protect your lips from sun damage with SPF lip balm, stay well-hydrated, and avoid excessive lip strain (like exaggerated puckering or whistling) to preserve results.

Cost of a Lip Flip

In the United States, the average cost ranges from $80 to $200 per session, depending on factors like your provider’s expertise, clinic location, and the number of units used.
Because the procedure is relatively affordable, many people choose it as a first step into cosmetic lip treatments.

Risks & Side Effects

While generally safe when performed by a qualified injector, a lip flip can have minor side effects. These include temporary redness, bruising, swelling, or difficulty using straws.
More serious side effects are rare but possible, such as asymmetry or over-relaxation of the muscle. Lip flips are not recommended for those who are pregnant or breastfeeding.

Is a Lip Flip Right for You?

This treatment works best for people looking for a modest improvement in lip shape, more visible upper lip, or reduced gum exposure when smiling.
If you want dramatic results or have significant asymmetry, fillers or a combination of treatments may be more appropriate.

How Often Should You Get a Lip Flip?

To maintain your look, most providers recommend repeating the treatment every two to four months. Some patients schedule theirs seasonally — for example, before summer vacations or big events.

Lip Flip Before and After — What’s Realistic?

A lip flip won’t give you a totally new mouth, but it can subtly refine your appearance. Your upper lip will look more relaxed, the pink part more prominent, and gummy smiles less noticeable.
Managing expectations is key — this is a finesse treatment, not a transformation.

Expert Tips to Maximize Your Lip Flip Duration

Choose a highly experienced injector who understands facial anatomy. Avoid alcohol and blood-thinning medications before your appointment to reduce bruising. Maintain a healthy lifestyle, protect your lips from the sun, and stay hydrated.
For those wanting both subtle shape change and added volume, pairing a lip flip with a small amount of filler can extend the results.
